Main Work of Primary Common Pilot Channel (PCPICH) in WCDMA is as below. Carrying pre-defined sequence Fixed channel code: Cch, 256, 0, Fixed rate 30Kbps Scrambled by the primary scrambling code Broadcast over the entire cell A phase reference for SCH, Primary CCPCH, AICH, PICH and downlink DPCH, Only one PCPICH per cell The Common … Read more
The S-SCH also consists of a code, the Secondary Synchronization Code (SSC) that indicates which of the 64 scrambling code groups the cell’s downlink scrambling code belongs to. 16 different SSCs are defined. Each SSC is a 256 chip long sequence. There is one specific SSC transmitted in each time slot, giving us a sequence … Read more
Work of Synchronization Channels P-SCH & SSCH in 3G WCDMA Synchronization Channel mainly Used for cell search its having Two sub channels: P-SCH and S-SCH, SCH is transmitted at the first 256 chips of every time slot. Primary synchronization code is transmitted repeatedly in each time slot. Secondary synchronization code specifies the scrambling code groups … Read more
While the goals and design targets specified above may be aggressive, options have been approved for consideration in the design that when used properly, will lead to a more efficient network compared to the existing 3G network. Therefore, in the quest to produce the best network possible in a cost-effective manner while meeting the goal … Read more
DL Cell Aggregate Throughput The DL Cell Aggregate throughput (Effective RLC Aggregate Throughput) is the sum of the throughputs to all the users in the cell at an instant in time. This is to be measured following Monte Carlo simulations only. Design KPI for DL Cell Aggregate Throughput: 10MHz Channel Bandwidth: 13.4 Mbps per cell … Read more
The overlapping zones (number of servers) criteria are used to establish the quality of the RF propagation environment from an interference point of view. The goal of the number of servers‘ criteria is to establish dominance and reduce the waste of network resources and degraded network performance that may occur when multiple servers exist in … Read more
Reference Signal Received Quality RSRQ identifies the quality of the Reference Signal. It is defined as the ratio N×RSRP/(E-UTRA carrier RSSI), where N is the number of RB”s of the E-UTRA carrier RSSI measurement bandwidth. The measurements in the numerator and denominator shall be made over the same set of resource blocks. E-UTRA Carrier Received … Read more
Reference signal received power (RSRP) identifies the signal level of the Reference Signal. It is defined as the linear average over the power contributions of the resource elements that carry cell-specific reference signals within the considered measurement frequency bandwidth. Design KPI for RSRP: 10MHz Channel Bandwidth (700MHz & AWS): -113dBm 5MHz Channel Bandwidth (700MHz & … Read more
What may be one of the biggest leaks phones in recent years, come from South Korean analyst, who published the alleged specs of both Samsung and Apple’s upcoming flagship smart phones. More troubling for Apple, including at least the hardware side, the device seems to more powerful handset Samsung handset. Is it enough to tempt … Read more
Sales of Apple’s iPhone 5c were so disappointing that the consumer technology giant will probably reduce the price soon device model or scrap altogether, according to analysts, Alistair Barr reports for USA Today. They just missed. The request was not good, said Gene Munster, an analyst at Piper Jaffray. They will discount and use it … Read more
